SPECIFICATION forming part of Letters Patent No. 584,515, dated June 15,1897. Application filed August 15, 1896. Serial No. 602,829. (No model.)

To aZZ whom, it may concern.-

' Be it known that 1, JAMES S. MERRITT, residing in the city and countyof Philadelphia and State of Pennsylvania, have invented an Improvementin Corner Plaster-Strips, of which the following is a specification.

My invention relates to corner plasterstrips; and it consists of theimprovements which are described in the following specification and areshown in the accompanying; drawings.

My invention relates particularly to an improved construction ofplasterers corner strips or plates, wherebya strong and efiicient stripmay be produced at the least possible cost.

It has been proposed in the construction of buildings to employ metalstrips secured to the framework at the corners and projecting out intothe angle of the corner for the purpose of supporting the plastering andforming a sharp corner. It has been usual to form such strips with a.series of perforations through which the plaster passes, forming bondsbetween the two faces of the plastering. As heretofore constructed therehas been a great waste of material in making these strips owing to theformation of the perforations. By my improvements in the construction ofthe strips lam able to reduce the waste to a minimum, forming two stripsfrom but little more material than was formerly required for one andwithout in any way decreasing the strength and efficiency of the strips.

In the accompanying drawings, Figure 1 is a perspective view of thecorner of the wall of a building employing my improved cornerstrip. Fig.2 is a plan view of a plate, showing the preferred manner of making thecorner-strips. Fig. 3 is a plan view of a portion of the corner-strip;and Fig. at is a transverse sectional View, on the line was of Fig. 1,of the corner of a building employing my improved corner-strip.

A is the usual vertical studding.

B is the lathing, and C the plaster.

D is the corner-strip, which is constructed with a continuous outer edged and a se ries of inwardly-projecting tongues cl, sepa rated from oneanother by intermediate open spaces (Z ing the strip.

In Fig. 2 I have shown the preferred manner of constructing thecorner-strips, whereby a minimum quantity of material is used. A stripof metal or other material of convenient length is punched or cut so asto be separated longitudinally into two corresponding pieces eachprovided with a continuous outer edge 61 and a series of projectingtongues d. In making these pieces the strip is out or punched at thelines a a'adjacent to each edge and transversely on the lines I) 1),connecting the opposite longitudinal cuts a a, thus forming the twoidentical pieces. In this way two corner-strips may be formed from asingle piece of material of but little greater width than has heretoforebeen used for making a single strip. The waste of metal in cutting thestrips is reduced to a minimum, and consequently the cost of manufactureis greatly reduced.

Vhile I have shown the tongues cl wedgeshaped, this is not essential, asthe lines I) b may be out or punched straight or inclining in theopposite directions,thus forming square or tapered tongues, or othershapes may be formed. I prefer the wedge shape shown, as it gives largeropenings 6 adjacent to the edge (1 for the plaster without in any wayweaken- The strip is fastened by the tongues cl to a strip E, secured tothe framework, or may be fastened, if desired, directly to the studdingA. The outer edge is left projecting beyond the studding or strip E, soas to form a continuous outer edge, with a se ries of openings 6 betweenthe outer edge (1 and the edge of the strip E or studding. Thisprojecting edge may be suitably bent, as shown in Figs. 1 and 2, tobisect the angle of the corner. The plaster is applied in the usualmanner and passes through the openings e, forming a bond between the twofaces.

In cases where a rounded corner is to be formed the outer edge of thestrip is suitably bent.

By properly bending the strip it may be used for either internal orexternal corners.

That I claim as new, and desire to secure by Letters Patent, is-

1. A corner plaster-strip composed of a piece of suitable materialhaving a continuous outer edge with a series of inwardly-pr0- ectingtongues separated from one another along the inner edge by openingsextending I into the body of the piece adjacent to the constrip ofmaterial on longitudinal lines co, (t, and

transverse lines I), 1), into two complementary pieces each having acontinuous outer edge d, and a series of inwardly-projecting tongues dseparated from one another 011 the inner edge by openings d 3. As a newarticle of manufacture, a corner-strip having a rib, with wingsprojecting therefrom at intervals, so spaced as to form openings throughwhich the plaster may eX- tend, substantially as described.

4. As a new article of manufacture, a corner-strip having a rib, withwings projecting therefrom at intervals and bent, so spaced as to formopenings through which the plaster may extend, substantially asdescribed.

In testimony of which invention I have hereunto set my hand.
